BrightGridUnderstanding the solar installation process makes it easier to compare installers and know what should happen after you request a quote. A professional project involves much more than putting panels on a roof.
1. Initial assessment
The process normally begins with information about the property, electricity consumption, roof, existing electrical system and future energy plans.
2. Roof and site survey
The installer assesses roof condition, dimensions, orientation, pitch, shading, access and potential panel locations.
3. System design
The design determines panel layout, inverter selection, cable routes, protection equipment, battery configuration and monitoring.
4. Grid and DNO requirements
Where required, the project follows the applicable grid-connection process. The requirements depend on the system and network connection.
5. Installation
Installation typically includes roof mounting, panels, cabling, inverter installation, electrical protection and optional battery or EV equipment.
6. Commissioning
The completed system is tested and configured. Monitoring systems are connected and the installer should explain how the system operates.
7. Handover
- Electrical certification
- System documentation
- Product warranties
- Monitoring access
- Operating instructions
- Relevant grid documentation
| Stage | Main objective |
|---|---|
| Assessment | Understand property and energy requirements |

| Commissioning | Test and configure the system |
| Handover | Provide documentation and customer training |
A good installation starts before the first panel reaches the roof
The quality of the survey, system design and electrical planning has a major influence on the final installation.

What happens during a solar installation?
A typical project includes assessment, survey, system design, applicable grid processes, installation, commissioning and handover.
How long does solar installation take?
The physical installation can often be completed relatively quickly, but the overall project timeline depends on design, equipment availability, grid requirements and property complexity.
Do solar installers provide certification?
A professional installation should include the relevant electrical and installation documentation.
Can batteries be installed at the same time?
Yes. Solar and battery systems can often be designed and installed together.
